| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In direct sequence code division multiple access (DS-CDMA), frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can achieve much better performance than the well-known rake combining. The conventional FDE requires the insertion of cyclic prefix (CP) into guard interval (GI). However, the CP insertion reduces the throughput. Recently, overlap FDE that requires no CP insertion was proposed. Another equalization technique is a time-domain sliding window chip equalizer (SWCE) based on MMSE criterion. In our previous paper, we evaluated and compared the bit error rate (BER) performances of multi-code DS-CDMA using SWCE and overlap FDE, and showed that overlap FDE can achieve almost the same BER performance as SWCE with much less computational complexity. In this paper, we evaluate by computer simulation and compare the throughput performances of DS-CDMA hybrid ARQ (HARQ) using overlap FDE and SWCE. | |
